How to learn to tell time? What books do you want to read on an auspicious day, such as getting married, building a house, making a bed, etc?

In fact, the problem you are talking about is reading almanac. If you read the almanac, it will be difficult to understand without certain practical experience, and it will be very sleepy when you look at it, because this kind of thing is really boring. If there is no in-depth research, I suggest you don't set foot in this industry. Unless you are very, very interested.
